摘　　要：冷阴极技术是磁控管发展的重要方向,冷阴极磁控管具有稳定性好、可靠性高、瞬间启动的特点。通过三种类型阴极磁控管冷启动特性对比分析,最终选择合金阴极作为冷阴极磁控管的发射体。采用合金阴极研制的磁控管,可以可靠地实现冷启动,起振稳定时间小于5 s,脉冲宽度、输出功率等电参数指标与传统热阴极一致。Cold cathode magnetron is an important direction of development which has good stability,high reliability quick start characteristics. Comparing the cold starting-up performance of three kind cold magnetrons,an alloy cathode is selected as the emitter of cold cathode magnetron finally. This alloy cathode magnetron could start up without filament and the starting-up time is less than 5 s. At the same time,pulse width and output power of this magnetron is in accordance with conventional thermionic cathode magnetron.
